This is severe, without tool docker bars (the left/bottom/right tool bars for the dockers), KDevelop is almost unusable. Needs to be investigated. I've seen this on fresh installs on Windows machines, Sven said it also happens on Linux. Reproducible: Always
The interesting thing is that this error is only visible on first startup, if you close kdevelop once and reopen it all is fine.
Git commit bb9dfe6dbee320fa3449675cd492d344fe9b60f4 by Sven Brauch. Committed on 26/06/2016 at 12:39. Pushed by brauch into branch '5.0'. Fix toolview hiding/showing I can't even begin to describe how broken this was: - emptyChanged() was not emitted when a button was added - there was a timer firing every 100ms, always (!) checking whether to show the toolview - once a toolview was hidden the member storing the state could never change such that it would show again CCMAIL:kfunk@kde.org This _probably_ fixes because I suspect it happens when the toolviews are constructed before plugins are loaded; then there are no buttons, and they are all hidden, and will never be shown again.
